I recently changed my dose of lithium (it went up) and since then, my period has not come. I'm approximately a week late and I'm having my normal premenstrual symptoms (tender breasts, cramps, pimples) but no bleeding whatsoever.
I went off Lamictal because it was making my periods very close together (approximately two weeks) and went off it two months ago. Is it possible that the change in dosage in lithium could be doing something similar?
Also, as I'm a virgin, I doubt the whole pregnancy thing could be in the cards.
